A question for those who own all or most of the packs (Expansion, and Game packs)

My main save is a huge rotational save so most sims are born there and throughout their childhood I think which direction they'll go. Last time I started a new save I actually used the story function and it did help me decide what type the sim was going to be. Overall I don't want to make too specific plans in CAS but let the live mode shape the sim. I only give them one outfit per category at start for example, so I can add later. Same with likes/dislikes.
